CH302 Spring 2009 Worksheet 2.
For Questions 14, use the Phase diagram below.
1. What is a good general definition of the term triple point? How many triple points are found int he
phase diagram for quartz shown above?
2. How many phase boundaries are there in the phase diagram for quartz shown above? (Hint: two of
them are found on the same line.)
3. Starting at 0.1 GPa and 200 °C and isobarically raising the temperature to 2000 °C, how many phase
transitions would occur? What would the final phase be?
4. What is a critical point? How many are shown in the phase diagram above?
5. Write as many assumptions involved in the derivation of the ClausiusClapeyron equation as you can.
6. Starting from the general ClausiusClapeyron equation and performing algebraic rearrangements,
express P
2
in terms of the other variables.
